Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we'll use ROE to better understand Sulzer Ltd (VTX:SUN).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Do You Calculate Return On Equity?

ROE can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Sulzer is:

2.7% = CHF28m ÷ CHF1.0b (Based on the trailing twelve months to December 2022).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each CHF1 of shareholders' capital it has, the company made CHF0.03 in profit.

Does Sulzer Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As shown in the graphic below, Sulzer has a lower ROE than the average (17%) in the Machinery industry classification.

Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved. Our risks dashboard should have the 2 risks we have identified for Sulzer.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

Combining Sulzer's Debt And Its 2.7% Return On Equity

Sulzer clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.34. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
